|Deriving Einstein's Mass - Energy Equation E = mc2 - Patrick Bruskiewich|
In a brilliant paper titled "Does the Inertia of a Body Depend upon its Energy-Content?" published in September 1905 in the German physics journal Annalen der Physik, 17, 1905 ("Ist die Tragheit eines Korpers von seinem Energiegehalt abha¤ngig?") Einstein was able to show that the mass of an object is a measure of its energy content. In this Ï - Physics Initiative in Education module Einstein's Mass-Energy Equation E = mc2 is derived and some of its implications are described...

|The Myth of Language and the Kind and Gentle Woman - Patrick Bruskiewich|
There is no greater myth that perpetuates the feminist mystique than the myth that woman are by their very nature kind, thoughtful and altruistic. In reality, they are after all human just like the men. Many feminists strive to perpetuate biased stereotypes and questionable assumptions both about what it is to be female, and about maleness, male anger and male aggression. A look at the nature of Total War and the Nuremberg Tribunal Findings, about who voted Hitler into power and why...

|The Time Reversal Operator and the Quantum Harmonic Oscillator - Patrick Bruskiewich|
In this paper, a pedagogical introduction to the Time Reversal Operator Î for the one-dimensional quantum harmonic oscillator (QHO) is presented. Time does not appear as a Hermitian Operator in Schrodinger's equation such as the position or the momentum operator does, time is merely a parameter. It is shown that the Time Reversal Operator Î is equal to K, the complex conjugate operator for the QHO.

Physical units are also known as dimensions in physics. Since the quantities represented by the two sides of an equation must have the same dimensions, it is often possible to arrive at the form of an expression connecting physical quantities by the consideration only of the dimensions of the quantities involved, without a detailed theory.
